It would have a mechanical advantage of 20, thus dividing the resistance force of 600N by the effort force of 30N.
Mechanical Advantage
Normally the force you apply. Load divided by effort is mechanical advantage.
1/4 the output force.
A machine's mechanical advantage is the number of times a machine multiplies the amount of work force you apply.

Mechanical Advantage
It may be good in some cases. A high mechanical advantage comes at a cost - you need to apply less force, but you need to apply it over a greater distance.

The purpose is to apply the force over a smaller distance.

A very practical example of mechanical advantage is the use of a "cheater bar." If you find a bolt that is hard to break, simply slip a long pipe or similar object over the handle and it will apply much more torque.
A pulley system is used to lift a 2,000 newton engine up a distance of 3 meters. How much force will the operator have to apply if the mechanical advantage of the pulley system is 4? mechanical advantage = 500 newtons.
A single pulley alters the direction of the input but confers no mechanical advantage.
